Měkkýši Jindřišského údolí u Jindřichova Hradce (jižní Čechy, Česká republika) [Molluscs of the Jindřišské údolí Valley near the town of Jindřichův Hradec (South Bohemia, Czech Republic)]

This paper presents the research of mollusc communities in the floodplain of Hamerský potok Brook (Nežárka River tributary, South Bohemia, Czech Republic). Altogether, 42 mollusc species (39 species of gastropods, three species of bivalves) were recorded in the study area during the research in 2015, representing 17% of the total Czech malacofauna. More than a half of all species represents common forest species, but several sensitive woodland species as Causa holosericea, Ena montana and Macrogastra plicatula and the vulnerable wetland species, such as Euconulus praticola were also found. The occurrence of these rare species (three near threatened and one vulnerable) makes the valley of Hamerský potok Brook an important mollusc refugium of prime conservation importance in this fragmented Bohemian landscape of a long-term agricultural land-use.
